Abstract: A finger roller for an agricultural implement has a shaft with a non-circular cross-section. Two or more finger disks are pushed onto the shaft in the axial direction of the shaft. The finger disks each have a hub with a central opening having an inner contour configured to match the cross-section of the shaft. The finger disks each have elastically deformable fingers connected to the hub. The fingers of each one of the finger disks are distributed uniformly about a circumference of the hub and project away from the hub. The shaft has a circumferential surface comprised of identical circumferential portions sequentially arranged in the circumferential direction of the shaft. The finger disks each have an odd number of fingers when the circumferential portions are even numbered, and the fingers disks each have an even number of fingers when the circumferential portions are odd numbered.

Title: Software migration on an active processing element
Inventor: ADAMOVITS PETER JOSEPH
IPC: G06F9/445
Filed: 2000-07-14
Abstract: An active processing element undergoes a software migration while under the control of an in-service original software system. A replacement software system is loaded into an available memory partition within the active processing element while the original software system continues to control the active processing element and its services. The original software system continues to control the active processing element as the replacement software system is configured and synchronized with the original software system. Once a set of dynamic state information within the replacement software system is synchronized to permit the replacement software to take control of at least a portion of the services supported by the processing element, control over such portion of services is transferred from the original software system to the replacement software system in response to a predetermined event such as a command from the system administrator or a fault condition detected in the original software system. As control over services provided by the processing element passes to the replacement software system, corresponding components of the original software system are placed in an inactive state. Once control over all services provided by the processing element is transferred to the replacement software system, the original software system is rendered fully inactive, although the original software system may continue to use processing resources of the processing element to support the remainder of the software migration, including transferring any remaining state information required by the replacement software system. An image of the original software system is stored on a migration archive for diagnosis.

Abstract: A methodology and devices for detecting or monitoring or identifying chemical or microbial analytes are described. The methodology comprises four basic steps: (1) The gas or liquid medium to be monitored or analyzed is brought into contact with a bioconcentrator which is used to bind with or collect and concentrate one or more analytes; (2) the bioconcentrator-analyte complex is then exposed to radiation of one or more predetermined wavelengths to produce Raman scattering spectral bands; (3) at least a portion of the Raman spectral bands are collected and processed by a Raman spectrometer to convert the same into an electrical signal; and (4) the electrical signal is processed to detect and identity, qualitatively and/or quantitatively, the analyte(s). The methodology of this invention may also comprise Raman reactive capacity analysis of the bioconcentrator itself, simultaneously with or independently from the detection of the analyte, to determine the potential ability of the bioconcentrator to complex with analytes; the results of this latter analysis may be used to affect or alter or modify the methodology involved in detection and analysis of the analytes. Also the invention is accomplished by a Raman Optrode comprising:  a bioconcentrator capable of binding with the analyte(s); a mechanism or procedure or device for bringing the gas or liquid sample into contact with the bioconcentrator, a light source suitable for generating Raman scattering; a Raman spectrometer capable of collecting and processing the Raman scattering spectral information and translating it into an electrical signal; and electronic hardware and software for analyzing the electrical signal and translating the signal into information on the presence, identity and/or quantity of the bound analytes.  Various forms of bioconcentrators are described, as well as a variety of analytes which may be detected, monitored, or identified by this invention, and a variety of devices which can be fabricated based on this invention.
